vent the ingress of sudden great gushes of.

wind and dust and the like.

Another very import-ant object of the invention resides in the provision of a ventilator of this nature which is easy to assemble. adjustable, and of a comparatively light structure.

A still further important object of the invention resides in the provision of a window ventilator of this nature that is exceedingly simple in its construction, strong and durable, inexpensive to manufacture, thoroughly efficient and reliable in use, and otherwise well adapted for the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arran ement of parts as will be hereinafter more fullyde'scribed and claimed.

In the drawing Figure 1 is a fragmentary outside elevation of a window showing my improved ventilator in place, v i

Figure 2 is a similar view showing the inside thereof,

Figure 3 is a sectional view through one section of the ventilator,

Figure 4 is a fragmentary sectional perspective of the other section'of the ventilator;

Referring to the drawings in detail it will be seen that the ventilator is formed in two sections, each being provided with a base plate 5 and a riser plate 6 disposed at an obtuse angle to the base plate 5 and extending from one longitudinal edge thereof. The

other longitudinal edge ofthe base plate is provided with a depending flange 7. One riser plate 6 has a rail 8 while the other riser plate has a rail 9 for slidably receiving the rail 8 so that the sections may be adjusted in relation to each other,;one overlapping the The ends of corners of the sections or the like 11 to be placed therein on the 'window sill as is shown to advantage in Figure 1. The outer sides of each riser plate is provided with a side plate '12 hinged along a diagonal line as at '13 to the edge of the riser plate so that these side platesmay be secured to the sides of the window frame with the bottom edges of the plates lying in substantially, the same plane. with the base plate 5, when the plates 12 are disposed perpendicularly to the riser plate 6, so that Whenthe side plates are securedto the window frame, the bottom edges and the base plate rest on the bottom of'the window frame. On the upper edges of the riser plates 6 there are formed angular beads 14. Flappers 15 are provided with curved upper edges 16 receivable in the beads so as to be capable of swinging movement in relation to the riser plate 6. The lower edges of the fiappers 15 are curved away from the riser plate 6 as is indicated at 17. It will be apparent that a sudden gush of wind will get under the curvedends 15. and raise the flappers so as to prevent the sudden gush ofwind from entering the room.

A standard 19 is hinged as at 20 to one. of the sections on the riser plate'6 as is illustrated in Figure 2 so that the same may be disposed angularly to the riser plate and brace the ventilator when in place from the inside of the window at the approximate center thereof.

It'is thought that the construction, utility, and advantages of the invention will be quite apparentto those skilled in thisart without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention" as hereinafter claimed or sacrificing any of its advantages.- Having thus described my invention what I claim as new is i 1. A. window ventilator structure of the class described comprising: a pair of sections,

each section comprising a base plate and a user plate extending therefrom at an obtuse angle, rails extending longitudinally of the riser plate and slidably engaged with each other, plates hingedly mounted to the outer side edges of the riser plates, the upper edges of the riser plates being formed with beads,

lie c-rs havin curved ed 'es mounted in the beads so that the flappers may swing.

2. A Window Ventilator structure of the class described comprising a pair oztsections, each section comprising a base plate and a riser plate extending therefrom at obtuse angle, rails extending longitudinally of the riser plate and slidably engaged with each other, plates hingedly mounted to the outer side edges of the riser plates, the upper edges of the riser plates being formed with beads, flappers having curved edges mounted in the beads so vthat the flapp'ers may swing, the lower free ends of thcfiappers being curved outwardly. v
